Patent number: 6725544Abstract: This creation is to provide a kind of anvil structure improvement for garden clippers. Such anvil is installed at the end of garden clippers' first handle, allowing the moving blade at the end of the second handle to oscillate into contact against the inner anvil surface of that anvil. The inner side of that anvil is a flat surface, the tip of which is in a position of jutting out from the tip of the moving blade. The anvil features a first cutting edge at the anvil's outer side, and a second cutting edge is further installed at the tip of the anvil. The provision of such first, second cutting edge adds extra functions of cutting, digging and drilling to the garden clippers as their primary applications.Type: GrantFiled: April 14, 2003Date of Patent: April 27, 2004Assignee: Jiin Haur Industrial Co., Ltd.Inventor: Shih-Piao Wu

Patent number: 6530099Abstract: A composite pliers has crossed levers, each including a non-metallic body with an exposed metal cutter blade. The pliers includes strengthening and/or retaining structure around a pivot joint which does not extend into handle portions of the levers. This structure strengthens the pivot joint and can help confine the pliers parts in the event of failure. In one embodiment, each lever has a pivot joint strengthening structure insert molded therein, the structure extending into a jaw portion of each lever and protruding from the non-metallic body to form a workpiece engagement surface, such as a cutting blade. In one form, the jaws have more than one row of teeth with adjacent rows offset from each other. When the pliers is assembled from two identical lever members, each row of teeth on one lever will face the offset row of teeth on the other lever so that the peaks of the teeth on one lever fall within the grooves between the teeth on the opposing row.Type: GrantFiled: July 19, 2000Date of Patent: March 11, 2003Assignee: Snap-on Technologies, Inc.Inventor: Dean J.

Patent number: 4637084Abstract: A crimping and cutting tool useable for cutting wire and connection of a ferrule tip type electrical connector to an electrically conductive wire. The tool includes first and second lever members pivotally connected with a pivot pin. Each lever member has a head with a cutting jaw and a crimping jaw and a handle. The crimping jaws have alternative teeth and recesses in opposition to one another. The crimping jaws are movable toward one another to crimping position by applying hand force on the levers wherein each of the teeth of one of the crimping jaws fills a recess of the opposite jaw. The recesses have differing sizes such that differing sizes of electrical connectors or ferrules can be accommodated in the recesses and crimped therein. Wire cutting jaws have convex curved cutting edges located above the pivot pin.Type: GrantFiled: December 6, 1984Date of Patent: January 20, 1987Inventor: Michael D. Wood

Patent number: 4459717Abstract: A compound tool for installation of a cable tie band. The elongated tool has a transversely disposed open-ended, rectangular slot that broadly approximates the tie band in cross-section and through which the free end of a loosely assembled tie band is threaded, firmly tensioned and finger clamped on the tool handle, the tool bottom being fulcrumed on the band at the tie head. The tool is then rotated to tighten the band and secure the bundle. A cutter blade, incorporated in the tool structure, is so pivotally mounted and configured that in the shearing of the excess of tie band, the blade initiates shearing at the outside edge of the band-slot assembly and continuously during shearing exerts only a clamping force which influences the tie band into the slot.Type: GrantFiled: September 15, 1983Date of Patent: July 17, 1984Assignee: Henry Mann IncorporatedInventor: William M. Halstead

Patent number: 4316315Abstract: This invention relates to a pair of double acting circlip pliers which consists of two jaw members which are pivotally connected intermediate their ends so that the free ends of the jaw members define first and second pairs of jaws on opposite sides of the pivot. The pliers further includes a pair of handle members which are freely rotatable about the pivot and adapted by means of suitably positioned formations to engage the first pair of jaws to operate the second pair when the handles are rotated towards each other in one direction and to engage the second pair to operate the first when the handles are rotated towards each other in the opposite direction.Type: GrantFiled: January 29, 1980Date of Patent: February 23, 1982Inventor: Josko Vogelnik
